Add __MACH__ as a Unix-like system (e.g. MacOS X defines __MACH__ but
no variant of __unix__.)

Correct the definition for MacOS classic "catsep" in nasm_catfile().
Also put in a stern comment that this function doesn't handle
filenames with path components.

Add a function to splice a pathname consisting of a directory and a
filename. It is worth noting that this function is limited to that
particular use case: in particular, it does NOT currently support
concatenating a filename which itself contains directory components to
a non-null directory.
Combining directory names is extremely system-dependent and probably
needs more than just parameterized code in many cases, for example,
on VMS combining "foo:[bar]" with "[baz]quux" should produce
"foo:[bar.baz]quux" whereas combining "foo:[bar]" and baz:quux" is an
outright error.

Some debugging formats may need to be able to split paths into
directory name and filename, at least. This is kind of iffy, at least
across platforms, but that isn't really expected to be an issue in
practice... we hope.
